A) Ah, so it's Swift continuing to suck. B) Why is device.formats double-bang? C) Why can't I option-click on formats in device.formats to get an answer (because A)? D) Why does command-clicking on formats take me to an Obj-C file (because A)? Thanks for pointing out you can get the type of a variable by option-clicking it like that. Not sure why it doesn't consistently work (e.g. why can't I get the type of formats), but that'll be very helpful. -- Rick Mann rm...@latencyzero.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
